NIACHINE FOR SETTING STAPLES, NAILS, 81.0.

SPECIFICATION formingpart-of Letters Patent No. 749,956, dated January19, 1904.

Application filed May 23, 1903.

To all whom it may concern:

Be it known that 1, CHARLES HENRY WIL- KINSON, residing at East Parade,Huddersfield, in the county of York, England, have invented '5 certainnew and useful Improvements in Machines for Setting Staples, Nails,Card-Teeth, and the Like; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableoth- IO ers skilled in the art to which it appertains to make and usethe same.

, The object of my invention is to set wire staples and the like in acircular or spiral arrangement, and this I accomplish by-attaching thework to an adjustable revolving spindle in such manner as to bringdifferent parts of the work successively opposite the stapling ortooth-setting device.

In applying my invention to, for example,

an ordinary or other. card-setting machine such as is used for fixingthe wire staples to card-clothing to form the teeth therein, as employedin textile manufactures, I may mount a revolving spindle, to which thework is at- 5 tached, in a bracket on a slotted sliding bar held inposition on any convenient part of the machine-frameby set-screws or thelike. The spindle may be caused to rotate by bevelgearing or othersuitable means driven, pref- 3 erably, by spur-gearing from the frontshaft or other convenient shaft of the machine.

Such being the nature and object of my said invention, I will nowexplain how the same may be carried into practical operation,

referring to the accompanying sheets of drawings, forming a part of thisspecification.

Figure 1 is an elevation of such parts of the driving end of an ordinarycard-setting machine as are necessary to. illustrate the application ofmy invention thereto. Fig. 2 is an elevation of my improved apparatus,taken at the front of such a machine. Fig. 3 is a plan of a portion ofsame on an enlarged scale. Figs. 4, 5, 6, and 7 are details hereinafterreferred to.

Referring first to Figs. 1 and 2, which represent the simplest form ofthe invention for setting staples radially in circles, number 1indicates the framework of the machine, 2 5 the main driving-shaft,which operates the by dotted lines.

The other arm, 6, of thelever 4-carries a pawl 7, the position of which in relation to the slot 8 in thelever-arm 6 is adjustable,

so that the pawl 7 may move the ratchet-wheel 9 one or more teeth, asdesired. The pawl 7 is kept down to its work by'a flat spring 1O.v

' The ratchet-wheel 9 is braked or kept steady by a weight 11, suitablyconnected to its shaft 5 or stud 12, and is prevented from running backby the lower pawl or catch 13, pressed into its teeth by spring 14;. Onthe shaft or stud 12 is a spur-wheel 15, which drives another spur-wheel16. The latter wheel 16 is 7 simply secured by a set-screw 17 onto thespindle 18, Fig. 2, and the wheel 15 is similarly secured onto itsshaft12. The slotted bar 19 is retained in the desired position on the ma:chine-frame by screws 20 21 passing through its slots, which allow oflateral adjustment, and this bar 19 supports brackets 22, 23, and 24,the two former carrying the spindle 18, while bracket 2 1 forms at itsupper extremitya cup, saddle, or socket for thework-spindle 86 25 torest upon, all these three brackets and parts in connection therewithbeing of course moved along with the said bar 19. Motion is communicatedfrom the spindle 18 to the work-' spindle 25 by means of bevel-pinions2627,- 5. T 3' tated so as to present a fresh portion of its surface toeach fresh staple 29 delivered to it. by the well-known settingmechanism. In 99 machines of this type a pair of needles'prick holes inthe work and retire, when a wire'staf ple is brought to the same placeand inserted into the holes so pricked; but to prevent the rubber beingdragged or plucked or fol lowing after the pricking-needles I may employsprings 30 and 31, which cover up aportion of the face of the rubberdisk and'oifer resistance to such plucking action. The bar 39 supportsthe back of the disk 28 against.

the impact of the needles. Also to prevent the work-spindle from dancingI may employ a curved spring 32, pressing said spindle down into thegroove or hollow formed in the socket at the top of the bracket 24, onwhich it rests, a small flat spring 33 projecting up from the bottom ofthe said bracket 24 and capable of pressing against the collar 34 on thespindle 25 if the said spindle moves forward, a flat spring 35 pressingdown on the other end of the spindle, and a sliding guardpiece 36capable of being moved to the left to bring it in contact with thespindle and there fixed by screws 37 38, (or by a wing-nut orthumb-screw,) which enter a convenient bar or plate 39, extending abovethe table of the machine, a guide 40 being provided at the side of saidsliding piece 36. The rubber disk 28 may be attached to the work-spindle25 by the means shown in Figs. 4 and 5namely, a screw 41, entering theend of the spindle,which may have a small metal disk 42 at or near theend thereof, and, if necessary, a washer 43 may be added to support therubber.

The mode of operation is as follows: The work being secured on the endof the spindle 25, the said spindle is slipped under the springs 32 and35 till it rests in its socket with its bevel-pinion 27 in gear withbevel-pinion 26 on spindle 18. The guard-piece 36 is slid up to thespindle and fixed by its screw or screws. The bar 19 is so adjusted thatthe axis of the disk and spindle is at the desired distance from thepoint at which the staples are to be inserted. The spur-wheel 16 isadjusted on the spindle 18 so as to be in gear with the spur-wheel 15.The pawl 7 is adjusted in the slot in the leverarm 6 so as to move theratchet-wheel 9 one, two, three, or four teeth to each revolution of themain shaft 2 in accordance with the speed of rotation intended to beconveyed to the work-spindle 25, this depending upon the distance apartat which it is desired to set the staples, and the machine started,rotating the work so that successive parts thereof are brought oppositethe setter. When the circle of staples in the disk is completed, theguard 36 can be drawn back and the work-spindle 25 slipped out fromunder its springs and the disk taken off. Where inner and outer rings ofstaples are required to be set on the same piece of work, this can alsobe done by the adjustment of the bar 19, as before mentioned, bringingthe axis of the work-spindle nearer to or farther from the point ofsetting. If it be desired to set the staples following the circumferenceof the circle, forming chords of small arcs instead of radially, asabove described, the top or bottom of the disk instead of one side willrequire to be brought opposite the staples, which are delivered in ahorizontal position, and therefore the slots for the adjustment of thebar 19 will require to be vertical, as shown in Fig. 6, instead ofhorizontal. Should the vertical movement be sufficient to interfere withthe proper engagement of the wheels 15 and 16, the latter can easily beremoved from its spindle 18 and replaced by a slightly larger or smallerwheel, as may be necessary.

Fig. 7 shows another modification. To set the teeth or staples in aspiral or helical arrangement, the bar must be slowly moved while thesetting is proceeding, this of course necessitating at least one of thewheels 15 or 16 being sufficiently broad to drive at all points of themovement of the latter. In this case the bar 19 is provided with eyes 4445, through which passes a screw-threaded rod 46, operated by a pulley47, and working through screw-threads in bearings 48 and 49 on themachine-frame, so that, the screws 20 21 being slackened, by turningslowly the said pulley the bar can be traversed in either direction. Theeyes 44 45 may, if preferred, be screw-threaded, and the bearings 48 49,with the portion of the rod 46 passing through them, may be plain, sothat the rod 46 keeps the same position and the bar travels along therod. The pulley 47 may be turned by hand or be automatically driven by astrap from any convenient rotating part of the machine, the size of thepulley 47 and of its driver being so arranged as to obtain the necessaryslowness of motion.

This invention is especially useful in setting wire staples inboot-heels, washers, and the like, but can also be used for settingnails and other metallic fastening or strengthening devices to variousarticles.

I claim as my invention 1. In a machine for setting or fixing staples,nails, card-teeth, and the like, the combination therewith of arevolving spindle to which the work is attached, such spindle beingcarried on a slotted bar capable of moving endwise and of being adjustedwhen the axis of rotation of the work-spindle is at the requiredhorizontal distance from the point of setting, for purposes described.
